MOVING BRICK-Dalian.

SPECIFICATION forming part of Letters Patent No 763,349, dated June 28, 1904.

Application filed February 16, 1904. Serial No. 193,851- (NO model-l T0 all 1,071,077?, it may concern:

Be it known that I, IRA P. ARMSTRONG, a citizen of the United States, residing at fallaceton, in the county of Clearfield and State of Pennsylvania, have invented aY new and useful Moving Brick-Driel, of which the following is a specification.

This invention relates to a movable endless conveyer adapted to carrying hand -molded bricks from the molding-table; and the object of the invention is to pass the said bricks while in transit from the molding-table over a highly-heated chamber, thereby drying the bricks.

My invention consists of the novel .features of construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings, in which- Figure l is a vertical longitudinal section through my device, the central portion being broken away. Fig. 2 is a plan view, the central portion being broken out and the conveyer being partly broken away to show the steampipes beneath. Fig. 3 is a transverse vertical section on the line 3 3 of Fig. l, the steampipes being removed. Fig. 4L is a detail inverted perspective view showing the construction of the conveyer.

In the drawings, A represents a frame of heavy timber or steel of considerable lengthfor example, one hundred feet-and capable of sustaining a weight of several thousand pounds. This frame practically constitutes a rectangular chamber having the outer Walls Al and the inner walls A2, an air-space being left between the walls. On the inner faces of the walls A2 are arranged parallel upper and lower tracks B, the lower set of tracks being arranged adjacent the bottom of the chamber and the upper set adjacent the top, the chamber being upwardly open. Adjacent each end of the frame and passing transversely through the sameare the parallel shafts C, arranged adjacent the bottomof the chamber, and the shafts C', arranged adjacent the top of the chamber. On these shafts, which are journaled in suitable bearings arranged between the walls A and A2, are sprocket-wheels C3, the bearing C2 of the shafts being shown -in elevation in Fig. 3, and it will be further noted that the sprocket-Wheels are arranged on the longitudinal axis of the frame A. I provide, further, a plurality of steel trucks D, having downwardly-anged end portions D, the trucks consisting of Hat steel plates bent downwardly at each end to form the flanges D, and each of these flanges has a square notch D2 formed on its lower edge. Riveted to each plate and having its end portions fitting in the said notches is a squared axle E, having a spindle portion at each end projecting beyond the trucks D and carrying a roller E', which roller is adapted to travel on the tracks B. A sprocket chain F is adapted to travel over the sprocket-wheels C3. The steel trucks D are secured to this chain, links of the chain being riveted to the axles E at distances of about three to five feet, and the trucks are spaced about one inch apart, and over the trucks and connected to each is a thin steel sheeting adapted to bend when the trucks, drawn by the chain, pass over the sprocket-wheels C. Arranged in this chamber formed by the frame A, or more especially by the sides A and A2 and by the steel sheeting Gr, forming the endless conveyer, is arranged a plurality of steam-pipes H, running lengthwise of the frame and adapted to heat the space inclosed by the sides A2 and the conveyer-body G, the double wall of the frame aiding in retaining the heat. The conveyer G travels continuously around these steam-pipes, over and below them, and becomes heated to a high temperature, and upon this heated conveyer are placed the bricks to be moved from the molding-table, the heat of the conveyer drying and hardening the bricks as they pass from one end of the frame to the other.

Any desired means may be employed for placing the bricks on the conveyer and for removing them from the conveyer.

Having thus fully described my invention, what I claim as new, and desire' to secure by Letters Patent, is-

1. The combination with a frame forming an upwardly-open chamber and having inner and outer walls, shafts arranged transversely in the said vframe and journaled at their ends IOO in bearings arranged between the inner and outer walls, sprockct-\vlicels on the said shafts, an endless conveyer adapted to travel over the said sprocket-wheels, and steam-pipes arranged in the chamber between the said sprocket-wheels, as and for the purpose set forth.

2. The combination with a frame, upper and lower parallel tracks carried by the frame, trucks, rollers carried by the trucks adapted to travel on the tracks, sprocket-wheels carried by the frame, a sprocketchain running over the said sprocketwheels, and an endless belt ot' metal sheeting secured to the upper faces of the trucks, thc said sprocket-chain boing secured at intervals to a portion of the trucks, as and for the purpose set forth.

3. A device of the kind described comprisinga steam-heated chamber, upper and lower parallel tracks arranged in the said chamber,

tracks, shafts arranged transversely in thel chamber adjacent the ends thereof, sprocketwheels on the shafts, a sprocket-chain adapted to run over the sprocket-wheels and secured to the trucks, and an endless conveyor supported by the .said trucks and adapted to travel with them, as and for the purpose set forth.
